Patentedin France June 3, 1888,110. 191,093; in Belgium September20,1888,N0.83,325 in England October 11, 1888, No. 14,593,- in ItalyDecember 31,1888,XLVIII, 24.345 in Spain January 10, 1889, No. 8,866,and in Austria-Hungary February 24, 1889, No. 39.

To all whom it may concern.-

Be it known that I, FRANQOIS TIQUET, a citizen of the French Republic,residing at Paris, in the French Republic, have invented certain new anduseful Improvements in and relating to Methods of and Machines forPrinting in Colors, (for which I have obtained Letters Patent in France,dated June 8, 1888, No. 191,093; in Belgium, dated September 20, 1888,-No. 83,325; in Great Britain, dated October 11, 1888, No. 14,593; inSpain, dated January 10, 1889, No. 8,866; in Italy, dated December 31,1888, No. 24,345, Vol. 48, and in Austria-Hungary, dated February 24,1889, No. 39, Fol. 502;) and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

The invention relates to the art of printing, and more especially tochromatic printing, and has for its object certain improve ments in themeans for obtaining impressions in different colors upon a continuousweb of paper or other fibrous or textile material and to a mode ofproviding the continuous web with register-holes.

To these ends the invention consists in the means for printing indiiferent colors upon a continuous web of material and in the mode ofsupporting the continuous web of fabric and adjusting the same on theprinting-cylinder, as will now be fully described, reference beinghad tothe accompanying drawings, in which- Figures 1 and 7 are side elevationsof so much of a chromatic-printing press as will be necessary to thefull comprehension of my invention. Figs. 2, 3, 4, and5 are detailviews, and Fig. 6 shows a portion of a web of material provided withadjusting-holes.

The general construction of the framing and the reciprocating table orbed for the stone or plate, the inking or the inking and wiping devices,and the mechanism for imparting motion to said devices and to theimpression or pressure cylinder are or may be substantially the same asin the chromatic printing-presses now in use, or they may be of anyother desired or preferred construction.

The impression-cylinder A has a transverse opening'or throat, in whichis fitted a suction-box N, of substantially rectangular form incross-section, the outer face of which is a segment of the circledescribed by the periphery of the cylinder and is so fitted in thetransverse slot or throat as to leave the surface of the cylinder Asubstantially unbroken and smooth. The box N is closed at both ends andits outer wall is perforated, and said box is in perpetual communicationwith the hollow shaft A of the cylinder A by means of one or moreradially-arranged tubes 0, as shown in Fig. 3. The tubular shaft A ofthe cylinder is closed at one end and its other end is in communicationwith any suitable exhaust apparatus by means of a pipe E, which isprovided with a three-way cock H. The plug of the three-way cock carriesa pinion h, that is in gear with a toothed sector K, automaticallyoperated from a driving element of the machine and a cam or cams oreccentric. M is a cross-bar whose under face has a cushion R, of rubberor felt or other like material, and is secured to a lever J, or a pairof such, said bar serving to press the web of paper onto the suction-boxN at the proper time and immediately thereafter move out of contact withsaid web of material.

Above the cylinder A and slightly to the left of its vertical diameterismounted a roller B, and immediately above the same a roller Z. At theright end of the machine is the feed-roll T, upon which is wound the webof material-to be printed, and at the left end of the machine is mounteda receiving-roll V, upon which the printed web is wound, a series ofintermediate guide-rolls a: cc :3 00 11: at being mounted in the framingabove the impression-cylinder for guiding theweb of material from thefeed-rollT to the printing devices and from the latter to the receivingor winding roll V. The number of these intermediate guide-rolls betweenthe printing roller or cylinder and the receiving or winding roller orcylinder may or will vary according as the material printed uponrequires more or less time to dry sufficiently so as to be wound on theroll. V without wiping or transferring.

In printing on such materials as require considerable time to dry Ipreferable use a web of suitable paper or blanket V and causethe same towind on the winding-roller V with the printed web of material. Thispaper web or blanket is wound on a roll X, mounted on the machine belowand slightly in rear of the winding-roller V, as shown in Fig.7. Thisperipheral speed of the printing-cylinder A and the rollers B, V, and Xmust be the same, and to attain this end the journal of the cylinder Acarries a gear-wheel P in gear with a wheel on roller B, the gearingbeing so proportioned that the roller B will have the same peripheralspeedas said cylinder, the roller V being driven by roller B, by meansof suitable belting I), so as to drive said roller V not only at thesame speed as the roller 13, but also in the same direction.

Inasmuch as the peripheral speed of roller V varies as the web winds onthe same, I provide a friction-brake, Fig. 5, for regulating the speedof said roller, which consists of a friction-disk G, rigidly secured tothe journal of the winding-roller V. In a bracket r, secured to the mainframe of the press, is formed a bearing for a brake-screw 0, providedwith a hand-wheel I, the screw 0, working in a threaded bearing formedin a brake L, constructed in the form of ayoke, whose arms are guided inthe bracket Q7 and carry a brakeshoe y in frictional contact with thedisk G. It will be readily seen that by applying the brake with greateror less force to the disk G the speed of rotation of the roller V can beregulated at pleasure.

The operation of printing on the web is as follows: The web of materialis provided along its opposite edges with register-holes co a b b c c d(Z, &c., adapted to engage two register-points i on theprinting-cylinder immediately behind the suction-box N relatively to thedirection of motion of said cylinder. The distance between theregister-holes a a b b, the, is equal to one-half of the development ofthe cylinder A, so that equidistant spaces of the web will receive theimpression, leaving equidistant blank spaces.

It fabrics are printed upon, the edges of the fabric F are preferablyprovided with a register-selvage consisting of a strip of paper P ,inwhich the register-holes a a b b, dam, that engage the register-points1', as above stated, are formed, said selvage strips being applied tothe fabric by means of beeswax and caused to adhere thereto by passingthe same between calendering-rolls. The register-holes are arranged inlines across the fabric at right angles to its motion, so as to properlyengage the register-points.

In starting the operation of printing, the web of paper is carried tothe printing-cylinder over the table T, thence over the guiderollsac m:0 to the guide-roll Z, around said guide-roll over the feed-roll B, andthe register-holes a a are engaged with the registerpoints by anattendant on each side of the machine, whose duty is to see that the webof material is in proper register and to correct any irregularitiesduring the progress of the Web of material to the printing-cylinder. Atthis moment the three-way cock is automatically operated to establishcommunication between the exhaust apparatus and the exhaustbOX N throughthe pipes F E, the hollow shaft A of cylinder A, and the tubular radialpipe or pipes (J, and simultaneously therewith the lever J decends andappresses the material to said exhaust-box, the suction causing saidmaterial to adhere firmly to the cylinder, the lever J immediatelyreturning to its normal position, this operation being repeated wheneverthe eXhaust-box reaches the proper position, or before an impression ismade on the web. When the cylinder A has revolved sufficiently to bringthe space between the register-holes a a into position for printing, thebed, with the stone, form, or plate, will have advanced sufficiently inits traversing movement to pass under the roller, and the said spacebetween the holes a and I) is printed in one color. At the same time thetoothed sector K is operated to move the plug of the three-way valve orcook to cut off the communication between the suction-box and exhaustapparatus and establish a communication between said box and theatmosphere to release the web of paper. As the space printed is equal toone-half of the development of the cylinder A, as above stated, thespace of the web of material between I) and 0 will be blank, while thespace between 0 and cl will be printed, and so on. The web of material\V passes under the feed-roll B, in contact with cylinder A, around saidfeed-roll to and over the guide-rolls 0c 00 50 .75 to the winding-rollV, the number of which may vary according to the length of time it isdesired to expose the printed surface to the atmosphere or to adrying-atmosphere before winding it on roll V, and, if desired, theguide-rolls m it w, &c., or some of them, may be heated in any usual orwell-known manner.

In order to prevent wiping or transferring in case the impressions arenot sufiiciently dry, I employ a roll X, on which is wound a web ofpaper W, of the same width as the web of material being printed, andcause the same to wind on the winding-roller with the said web of paperIV to take such transfer and prevent wiping.

After the web WV or the webs W and W are wound on roller V they areremoved from their bearings, as is also the empty roll T, the rollVtaking the place of roll T and the latter roll that of roll V, the rollX being mounted in bearings at the feed end of the machine below roll Vin case a web of paper W is employed, and a roll X, containing such aweb of paper W, is mounted in the bearings of roll X. By a properadjustment of the Web W on the cylinder A the spaces previously printedmay now receive a second impression in a different color, or the blankspaces may now be printed, as desired, and as the web W unwinds fromroll V the web W is wound on roll X. Thus in printing in the web withoutcutting up two rolls are used that serve alternately as feed andreceiving rolls, inconjunction with which two auxiliary rollsX and X arerequired in making the first two impressions when a drying-web of paperor blanket W is employed-namely, a feed-roll X, containing the blanketWV, which after the first impression is transferred to the feed end ofthe machine to receive the web W, wound with web W on roll V, a secondroll, containing a blanket W, being applied at the delivery end of themachine to wind with web WV on roller T during the second impression,after which the said rolls X and X are alter nately transferred fromdelivery to feed end, for the purposes set forth.

I am aware that suction has heretofore been resorted to to cause a webof material to adhere to the printing-cylinder, and I do not desire toclaim the use of suction, broadly. Inasmuch as this is well known, Ihave deemed it unnecessary to show the suction apparatus.

Having now described my invention, what I claim is 1. In achromatic-printing press, the combination, with a reciprocating bedcarrying the stone, form, or plate, and a revoluble printing-cylinderprovided with suitable register-points and a suction-box N, extendingacross the face of the cylinder, of a lever J, co-operating with saidsuction-box to appress the material printed upon to said box, adelivery-roll on one side of the cylinder, a feedroll above and incontact with said cylinder, a winding-roll on the opposite side of thecylinder, and suitable guide-rolls, substantially as and for thepurposes specified.

2. In the art of printing textiles in the web, the mode of supportingthe web of fabric and adjusting the same on the printing-cylinder, Whichconsists in cementing to each of the opposite edges of the web of fabrica strip of points and with a suction-box N, extending across the facethereof, of the lever J, adapted to co-operate with said suction-box toappress the material printed upon to said box, a delivery-roll on oneside of the cylinder, a feedroll above and in contact with saidcylinder, a winding-roll on the opposite side of the cylinder, andsuitable guide-rolls, said feed and winding rolls being geared togetherand to the cylinder so as to revolve at the same peripheral speed,substantially as and for the purposes speoified.

4. The combination, with the printing-cylinder A and the feed-roll B, ofthe windingroll V, the friction-disk G on the journal of said roll, theyoke-brake L, the brake-screw 0, operating in a screw-threaded bearingof the yoke-brake, and a'support and guide for said screw and brake,substantially as and for the purposes specified.

In testimony that I claim the foregoing I have hereunto set my hand this7th day. of November, 1888.
